AI Market Summary

Strong diesel efficiency and typically 45–50 mpg real-world; C-Class holds residual value well in Ireland's premium market.
Fairly priced at median for this age/mileage; +27.6% YoY suggests steady demand—not overheated, but not a bargain.
Diesel engines (2021 OM 654 unit) are proven; no widespread defects reported. Service intervals long (20k km). Check full service history.
Inspect exhaust particulate filter (DPF) condition and confirm selective catalytic reduction (AdBlue) system functioning—critical on higher-mileage examples near 100k km.
NI import saves €6,326 before VRT applies on top; final cost still competitive against RoI stock after tax and registration.
